hardware solution for designs that demand high capacity and bandwidth memory

interfacing, ultra-low latency communication, and power efficiency. With a full-height,

half length form-factor package, the TR10a-HL2 is designed for the most demanding

high-end applications, empowered with the top-of-the-line Altera Arria 10 GX,

delivering the best system-level integration and flexibility in the industry.

The Arria® 10 GX FPGA features integrated transceivers that transfer at a maximum of

12.5 Gbps, allowing the TR10a-HL2 to be fully compliant with version 3.0 of the PCI

Express standard, as well as allowing an ultra low-latency, straight connections to four

external 40G QSFP+ modules. Not relying on an external PHY will accelerate

mainstream development of network applications enabling customers to deploy

designs for a broad range of high-speed connectivity applications. For designs that

demand high capacity and high speed for memory and storage, the TR10a-HL2

delivers with six independent banks of QDRII+ SRAM, high-speed parallel flash

memory. The feature-set of the TR10a-HL2 fully supports all high-intensity applications

such as low-latency trading, cloud computing, high-performance computing, data

2.4 Temperature Sensor and Fan Control

The FPGA board is equipped with a temperature sensor, TMP441, which provides

temperature sensing. These functions are accomplished by connecting the

temperature sensor to the internal temperature sensing diode of the Arria 10 GX device.

The temperature status and holding configuration information registers of the

temperature sensor can be programmed by a two-wire SMBus, which is connected to

16

the Arria 10 GX FPGA. In addition, the 7-bit POR slave address for this sensor is set to

‘0011100b’.Figure 2-7 shows the connection between the temperature sensor and the

Arria 10 GX FPGA.

Figure 2-7 Connections between the temperature sensor and the Arria 10 GX

FPGA

An optional 3-pin +12V fan located on J15 of the FPGA board is intended to reduce the

temperature of the FPGA. The board is equipped with a Fan-Speed regulator and

monitor, MAX6650, through an I2C interface, Users regulate and monitor the speed of

fan depending on the measured system temperature. Figure 2-8 shows the connection

between the Fan-Speed Regulator and Monitor and the Arria 10 GX FPGA.

The TR10a-HL2 has implemented a power monitor chip to monitor the board input

power voltage and current. Figure 2-9 shows the connection between the power

monitor chip and the Arria 10 GX FPGA. The power monitor chip monitors both shunt

voltage drops and board input power voltage allows user to monitor the total board

power consumption. Programmable calibration value, conversion times, and averaging,

combined with an internal multiplier, enable direct readouts of current in amperes and

power in watts. Table 2-7 shows the pin assignment of power monitor I2C bus.

2.6 Clock Circuit

The development board includes four 50 MHz oscillators and two programmable clock

generators. Figure 2-10 shows the default frequencies of on-board all external clocks

going to the Arria 10 GX FPGA.

Figure 2-10 Clock circuit of the FPGA Board

A clock buffer is used to duplicate the 50 MHz oscillator, so there are six 50MHz clocks

fed into different five FPGA banks. The two programming clock generators are low-jitter

oscillators which are used to provide special and high quality clock signals for

high-speed transceivers and high bandwidth memory. Through I2C serial interface, the

clock generator controllers in the Arria 10 GX FPGA can be used to program the

19

Si5340A and Si5340B to generate 40G Ethernet QSFP+ and high bandwidth memory

reference clocks respectively.
